In general, yes.
In the specific case of 16 versus 10, and only in thise case, if you hit 16 via multiple cards, it's better to stand. Unless one of those cards is a 6, in which case you should hit, unless two cards are 5s and one is a 6, in which case you should stand.
It's that close of a call.
Also, it makes an almost unmeasurable difference in your long term results.
